Hey guys,

the KnightOS team having started (more than started actually) working on z80e, a z80 emulator written in C, and after me porting it to Windows (it uses SDL), I thought about porting it to the TI-Nspire. And guess what ? I did

Be warned : the emulator itself not being finished, the Nspire version isn't either. Of course, I plan to mirror progress that's being made on the PC version to the Nspire version.

So far it doesn't actually run the TI-OS, but it does run the attached KnightOS ROM. You'll still see that some things aren't right, but that's really the emulator's fault. Also, it'll work both with Ndless 3.1 and Ndless 3.6, the PRG version being for Ndless 3.1.
I don't release the code yet because I still have a huuuuuge lot of clean-up to do, due to the Nspire not using many features that the PC version uses (like the CLI debugger).

But yeah, do check out the attachements. Please let me know about any bug that might crash or freeze your calc, and in what circumstances. Those may be known emulation problems, or not.

EDIT : oops, forgot to put control scheme.

So yeah, control scheme so far :

TI-84+SE key	TI-Nspire key
F1	A
F2	B
F3	C
F4	D
F5	E
Down, left, right, up	Down, left, right, up (click on touchpad calcs)
2nd	Ctrl
Alpha	Shift
Enter	Enter
Clear	Menu
Mode	Esc
Del	Del
Numkeys	Same numkeys
ON	Tab

You can exit the emulator at any time by pressing Q. If it doesn't work, then that's pretty much that the emulator itself is stuck, and not the emulation.

EDIT 2 : screenshot ! How could I have forgotten that.



EDIT 3 : dayum, forgot to compile with -Ofast. Attachment updated !

SecONd!
Edit: first edit!

Is this eventually going to be able to emulate TI-OS?

You should load TI-Boy up, port the emulator to emscripten, and run the emulator in a Bochs so that you can run an emulated GameBoy in an emulated TI-83+ in an emulated in Nspire in an cross-compiled Javascript in an emulated PC.

So far, the difference is that this one is actually being worked on, since the one you posted is dead. For now, it's less feature-fledged though, but that will come with time.

Yeah it's sad to have Jacobly gone, calcemu could have been fantastic

They are being emulated. z80e aims to be 100% compatible with everything.

Do you have any plans to push your changes back to the z80e repo?
